What kind of Collimation can a GSO RC DO?

The GSO RC allows three adjustments: a) The optical axis (primary mirror) and focuser vs the tube axis (step 2). This requires normally no adjustment. Unfortunately the focus tube vs. primary mirror is not adjustable (step 1). b) Secondary mirror collimation. This could require adjustment and normally the only adjustment you should make.(step 3)

How to collimate a GSO Ritchey Chretien telescope?

If your not satisfied with the telescope performance, do all five steps/checks as follows: Step 1) Primary mirror vs focuser tube:First step is to check and adjust the alignment of the focusser with the primary mirror. This is easy if the back cell is removed.

Can You collimate a GSO with a barlowed mirror?

Note that an RC has two adjustable mirrors. I used a collimation laser with an 1mm barlowed attachment to have a sharp laser point. Note that looking at a 5 mw laser point could irreversible damage your eyes. The GSO RC allows three adjustments: a) The optical axis (primary mirror) and focuser vs the tube axis (step 2).

When do you collimate your SCT rod Mollise?

If yes, you’re done. But if the rings seem “skewed” to one side or another, you’ve got more collimatin’ to do, pardner. Adjust your secondary (by very small amounts) until the rings are concentric . When you adjust the secondary, this will decenter the star in your field. Always recenter the star carefully before making a further adjustments .

What are the effects of collimation in radiography?

Collimation Effects X-ray beam collimation for radiography and fluoroscopy projection imaging is important for patient dose and image quality reasons. Actively collimating to the volume of interest reduces the overall integral dose to the patient and thus minimizes the radiation risk.
